It's better to try and not separate them when they are little as often trying to separate them is more damaging. When I transplant my seedlings I use tiny crusts of the potting soil with seedlings attached. That way they aren't as stressed.

By the next spring the seedling bed is SOLID anyway. You will be shocked at how much they grow.

Sorry I just kind of dropped this, life gets in the way of my fun stuff.
Those are 2 separate rosettes. Here is another picture with a quarter for size reference.
There is actually one more in there as well but still very small.
I'm way behind as I just lined these out a few days ago.
Next to these 'Gold Bug' seedlings are some from Brown owl.

Boy, that's a lot of seedlings! I have only about 200 left, all singles although some have developed double or even triple rosettes - mostly green and in various diameters.
I actually lost some due to early transplant/ separation combined with direct sunlight and heat. I should have kept them more in the shade.
Julia, I see some nice red tips in the center cluster on the first 'Gizmo' group photo!

Yes, saw that as well. There are several like that in that group of seedlings. We are just getting a few cool evenings so should expect more coloration as fall processes into winter. 'Gizmo' and 'fuzzy Wizzy' seedlings have been planted since July. Hope the rains hold off here so this next group have a chance to root. I had to create a new space for 'gold bug and 'brown owl' that's the reason for the delay.
